Food grade silicone certification is the German LFGB, the US FDA certification.

Food grade silica gel is made of silicic acid polycondensation of inorganic polymer colloidal material, the main component is SiO2? NH2O, its content in more than 98%, non-toxic and tasteless, chemical stability. Can withstand 220 ℃ high temperature, can be used in the microwave oven, Food Grade Silicone Rubber the human body without any side effects. Compared to other materials, with safer and more healthy features. For example, common plastic in the production must be added to a large number of antioxidants, plasticizers, stabilizers, Food Grade Silicone Rubber these additives are harmful to the human body, and plastic in high temperature conditions will make environmental hormones exudate and in the body fat Accumulate in the organization. In simple terms, food-grade silicone has a strong stability properties, and more in line with health and safety requirements. In fact, Food Grade Silicone Rubber in the ordinary people home has a trace of food-grade silica gel, the most common is the pressure cooker for sealing the gasket, easy to clean and non-toxic harmless.

Food grade silica gel is made of silicic acid polycondensation of inorganic polymer colloidal material, the main component is SiO2 · nH2O, its content in more than 98%, non-toxic and tasteless, chemical stability, in addition to normal caustic and hydrofluoric acid , And does not react with any acid and alkali salt. Food Grade Silicone Rubber Because it is a colloidal structure, it has many micropores and a large specific surface area. Edible silicone pore size of about 8-10nm, specific surface area of 300-500m2 / g, and the surface of hydrophilic, Food Grade Silicone Rubber water has a strong absorption capacity, in the case of high humidity water up to its own weight of 80% -100% The So the food grade of silica gel can be used as food, medicine, topical desiccant. As the edible silica gel is refined and sterilized, and food and pharmaceutical products can be mixed after the need to directly ensure the dry food and food with food, and the human body without any side effects.
